Dementia screening tools are used to screen for cognitive impairment, diagnosis of dementia and document change over time. These tests will help to decipher if someone has normal age related memory problems or more severe type of memory problems.
Objectives: The objectives of this page are to:
1 Learn more about dementia screening tools 2 Learn how to administer dementia screening tests 3 Learn how assessments are scored and cut off criteria 4 Learn the validity of the tests 5 Learn what test to choose for different populations
Screening Tools
The Abbreviated Mental Test Score (AMTS) GOLD STANDARD FOR CLINICAL DIAGNOSIS 10 items scored with either a 0 or 1. 0= didn’t answer question correctly 1= correct answer
Assess orientation, registration, recall and concentration
Any clinician is able to administer test
Takes approximately 3-4 min to complete
Available on mobile application
Scoring Max score =10 > 6 = Normal 4-6 = Moderate impairment 0-3 = Severe impairment
Validity Specificity: .95 Sensitivity: .79 * Low positive predicative value, need second assessment to confirm diagnosis
